If you use BitTorrent, when it says the transfer is done, you know it's not only done but bit-perfect.
There's nothing special about BitTorrent in this regard. If you use any protocol based on TCP/IP, such as HTTP, then you get the same checksum calculations. Packets with bad checksums are discarded and retransmitted. When done, you have a bit-perfect file.
The RAM is soldered in so I can't expand it, for no good reason that I can think of.
Because a RAM DIMM socket is a common point of failure. I once saw an old Macbook Pro with such a socket dropped onto a concrete floor. Afterward, it would not boot. It turned out that the RAM DIMM was slightly dislodged from its socket.
DIMM sockets are acceptable for desktop machines that don't move and are not subject to shocks. Laptops require more robustness.
